Do not under- nor overestimate your importance in this world. For all that you are and all that you have belongs to the Universe, even your very life.
Your intrinsic value is equal to that of any other being because you share it with every being. Your worth is immeasurable. And there is nothing you can ever do or say that can add to or take away from that perfection with which you were created. Understand this and you will recognize equality. Live this and you will achieve humility.
